How to custom-refresh data onExport

[hepcat72]

Description

I am not using the built-in server-side pagination, which is a separate issue^. I am using my own server-side pagination by sending queries to my Django view onSort, onSearch, and onColumnSearch, which uses the BST options (limit, offset, search, order, and sort [and some yet-to-be-developed column search params]) to retrieve a page's worth of a Django object_list QuerySet data for display.

I would like to add an onExport event code to grab all the JSON data for export. I.e. Let's say I would have 1000 pages, but the only data currently present is 10 rows worth. Since I'm not using the built-in server-side pagination, how can I retrieve that JSON data and make the export operate on it instead of on the data currently displayed in the django template? Is that possible?

I realized that if I used the same mechanism to retrieve the Django QuerySet object containing all of the data to populate the page, it would interrupt the export operation, though perhaps upon page load, I could call the export... (I'm still thinking this through.)

^ I want to use a django template to render the table rows, but when I use the built-in server-side pagination, it replaces my customized row template with the retrieved JSON data without all of the template decorations.

Here's my clunky work-around. Since I cannot get the clicked export type and trigger a full download after updating the page, I just have the user confirm their intent. If they want all data, they have to follow the instructions:

        function exportMessage() {
            if ({{ limit }} !== 0 && {{ limit }} !== {{ page_obj.paginator.object_list.count }}) {
                if (confirm("Download 1 page?\n\nTo retrieve all data, cancel and select 'ALL' from the rows per page select list below and try again.")) {
                    console.log("Downloading page {{ page_obj.number }}.");
                } else {
                    throw new Error("Canceling download");
                }
            }
        }

        document.addEventListener("DOMContentLoaded", function(){
            $('#file_list').bootstrapTable({
                onExportStarted: function (event) {
                    exportMessage();
                },
        });

I have to throw an error to cancel the download, since I can't seem to automatically load the full data by changing the URL.
